Answer:
All real numbers are solutions.
Step-by-step explanation:
Let's solve your equation step-by-step.
−28+4x=4(x−7)
Step 1: Simplify both sides of the equation.
−28+4x=4(x−7)
−28+4x=(4)(x)+(4)(−7)(Distribute)
−28+4x=4x+−28
4x−28=4x−28
Step 2: Subtract 4x from both sides.
4x−28−4x=4x−28−4x
−28=−28
Step 3: Add 28 to both sides.
−28+28=−28+28
0=0
Answer:
All real numbers are solutions.
<3
Answer:
D. |-10| < |12| < |-15| < |17|
10 is less than 12, which is less than 15, which is less than 17.
Step-by-step explanation:
A. |-10| |-10| > |-12| > |17|
12 is not greater than 17.
C. |10| > |-15| > |-5| > |2|
5 is not greater than 2.
22/5 = 4.4 (also correct as written: 4.40)
Therefore,
4 dollars and 40 cents
Written in a fraction it would be 44/10.
Answer:
18 like both.
Step-by-step explanation:
If there are 50 students and 3 like neither math or physics, then 47 of them either like one or both of the subjects. Adding up the 30 and 35, we get that 65 of the students like the two subjects collectively. Well that’s not right. We have overcounted the 65–47=18 students who like both subjects. Thus, 35–18=17 students only like physics.
Check: We have 3 students who like neither, 18 who like both, 17 who like just physics, and 30–18=12 who just like math. Adding them up, we have 18+17+12+3=50 students all togtether
Answer: y=4
Step-by-step explanation: First of all, we have to know what a consistent and independent system is.
Consistent and independent- If a consistent system has exactly one solution, and is independent, then it's consistent and independent
Let's graph the equation y=3x-2 first. The y intercept of the equation is -2 and the slope of the equation is 3. Lets plot the y intercept first, then use rise/run for the slope. We end off with the image of the first one I have attached to this answer.
Next, we can see if that we draw a straight arrow to one of the points in the equation, we will get a independent and consistent system. I picked y=4, but you can pick almost any point that lies within the line.
This will grant only one solution, which will give us what we need. So let's graph y=4. Finally, we have our consistent and independent system! I've attached another file to support my answer.
So the final answer to your question is y=4, the solution to the system is (2,4), as you can see by the last image.
